It is formerly known in connection with skis to protect the edges of the running. surface or to produce sharp and hard edges thereon by securing on the same strips of fiber, metal or other suitable material, which strips extend in the longitudinal direction of the ski and are placed into grooves formed in the running surface so that they lie level with said surface.

However, the placing of such strips in the running surface makes it impossible to smear said surface in an effective manner, at the same time as the strips in special conditions of skiing roads, easily will cause formation of ice. It has also been proposed to use in cross section angle shaped strips which enclose the lower side edges of the ski, but such strips stiffen the ski in such a manner that it loses its elasticity.

The present invention relates to a ski edge protector by means of which the above named drawbacks are removed, and the invention is mainly distinguished thereby that the protector consists of relatively short pieces or links which are secured in the elongation of one another to the side of the ski.

In preparing the protector in this manner the ski, irrespective of the cross section of the protecto-r, retains its original elasticity at the same time as the single pieces or links when worn out may be replaced with new ones.

The invention is illustrated by way of example in the accompanying drawing in which,

Figure 1 shows a cross section of a ski provided with a protector according to the invention,

Figure '2 shows a portion of the ski seen fromthe side thereof,

Figure 3 shows a longitudinal section of one of the links,

Figures 4-6 show different embodiments of adjacent ends of the pieces or links, 7

Figure 7 shows a modified embodiment,

Figure 8 is a top plan view of the links as shown in Figure 5; and

Figure 9 is a top plan view of the links as shown in Figure 6.

In the drawing l denotes the ski, which on each side is provided with a groove 2 extending in the longitudinal direction of the ski, which groove is open against the running surface and adapted to receive the protector. According to the invention said protector consists of a number of pieces or links 3 which are secured in the elongation of one another to the ski by means of screws 4 screwed into the side thereof. The links or pieces shown are respectively short and of one and the same length.

edge for the purpose aimed at.

December 21, 1933 In the embodiment shown in Figures 1-3 the ends of the links are rounded after semi-circular arcs and the end portions are thinned or provided with sunk portions 5, so that they can overlap each other and still be situated in the same 5 plane, at the same time as two adjacent ends may be secured by means of a common screw 4'.

As will be understood the links may be interconnected, by means of rivets or the like, in the elongation of one another so that they form a n strip which is bendable in a direction parallel with its plane, and this strip then is secured to the ski in the described manner.

Instead of interconnecting the links as de-- scribed above, the links may be secured on the ski in the elongation of one another as shown as .an example in Figures 4-6. In Figure 4 the links abut each other, and one or both of the adjacent ends is or are beveled so that a limited swinging movement of the links in the vertical A plane is made possible during the springing of the ski. In Figure 5 the abutting ends of the links are arch-shaped rounded, at the same time as the end surfaces constitute an acute angle with the side of the ski. In Figure 6 one of the links is provided with a slot for a corresponding projection on the adjacent link, and the connection is so shaped that the above described movement between the links is possible.

When the edge protector is prepared as above described it will-irrespectively of the stiffness V in the material from which it is manufactured and of the cross-section of the links-be bendable in its longitudinal direction to such a degree that it will not act restrictive for the elasticity of the ski, and it will also easily follow the varying bending as a ski, owing to its form and use, may be exposed to in its longitudinal direction. As a result it is also possible to provide the links with an angle-flange 3 which protrudes into a usual groove in the running surface of the ski as shown to the left in Figure 1. Further this angle-flange, by turning the links upside down, may be brought to protrude into a slit formed for that purpose in the side of the ski, as shown in Figure 7.

As will be understood the cross-section of the links and the shape of the ends thereof may be given any suitable form when only the above described mutual movement of the links is made r possible so that the elasticity of the ski is retained, and so that the outer side edge of the links, which is parallel with the running surface of the ski, constitutes a durable, sharp and hard 3. Ski edge protector according to claim 1, in which the ends of the links are provided with thinned or sunk portions by means of which they overlap each other so that adjacent ends may be secured to the ski by means of a common screw.

4. Ski edge protector according to claim 1, in which the links at one of their side edges are provided with an angle flange.
